Answer:
C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Step-by-step explanation:
In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.
Now let use an example to drive this;
Given:
2x - 9 = x + 8
This is an equation, and what we have on both sides should be equal.
Collect like terms;
2x - x = 8 + 9
x = 17
So the solution is 17.
This is the best way to solve an equation.
Jeremiah filled up his car with gas before embarking on a road trip across the country.

A ball is thrown from the top row of seats in a stadium. The function
ℎ()=−162+64+80
gives the height, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground
Answer:
It will be 5 seconds before the ball hits the ground
Step-by-step explanation:
∵ A ball is thrown from the top row of seats in a stadium
∵ The function
∵ h(t) = −16t² + 64t + 80 , gives the height, in feet, of the ball t seconds
after it is thrown
∵ The ball hits the ground
→ That means h(t) = 0
∵ h(t) = 0
∴ 0 = -16t² + 64t + 80
→ Reverse the two sides
∴ -16t² + 64t + 80 = 0
→ Divide both sides by -16 to simplify it
∵ [tex]\frac{-16t^{2}}{-16}+\frac{64t}{-16}+\frac{80}{-16}=\frac{0}{-16}[/tex]
∴ t² - 4t - 5 = 0
→ Factorize it into two factors
∵ t² = t × t
∵ -5 = -5 × 1
∵ -5t + 1t = -4t ⇒ the middle term
→ The factors are (t - 5) and (t + 1)
∴ (t - 5)(t + 1) = 0
→ Equate each factor by 0 to find t
∵ t - 5 = 0
→ Add 5 to both sides
∴ t = 5
∵ t + 1 = 0
→ Subtract 1 from both sides
∴ t = -1 ⇒ rejected because no negative value for the time
∵ t = 5
∴ It will be 5 seconds before the ball hits the ground
jack has $7.55 of change in his pocket. if he has 4 more dimes than than nickels, and twice as many quarters as nickels, how many of each coin does jack have
Answer:
11 nickels, 15 dimes, 22 quarters
Step-by-step explanation:
number of nickels = x
number of dimes = x+4
number of quarters = 2x
- - - - - -
total of nickels = 5x cents
total of dimes = 10x + 40 cents
total of quarters = 50x cents
- - - - - -
755 = 5x + 10x + 40 + 50x
755 = 65x + 40
715 = 65x
x = 11
x+4 = 15
2x = 22

jina runs 4 miles in 30 minutes. at the same rate, how many miles would she run in 48 minutes
Answer:
6.4
Step-by-step explanation:
You want to divide 30 by 4 to figure out the rate.
30 / 4 = 7.5
Now you divide again, taking the 48 into the equation.
48 / 7.5 = 6.4
Jina would run 6.4 miles in 48 minutes, following the same rate.

In the diagram, △ABC ~ △DEF. What is AC?
The image is of two similar right triangles ABC and DEF with right angles at B and E respectively. First one smaller in size and its base is 3. Base, altitude and hypotenuse of second one are 6, 8 and 10 respectively.
A. 4
B. 7.5
C. 5
D. 3
Answer:5
Step-by-step explanation: If you look at the base of both triangles, you'll notice that the smaller one has a base of 3, and the bigger one has a base of 6. The smaller triangle is half of the big one, therefore we can safely say that the hypothenuse of the smaller triangle is half of that of the larger one. Half of 10 is 5.
I had the same question on my homework.
A jeweler has 160.5 centimeters of gold chain. He will use half of the chain to make a necklace. He will make 5 bracelets with the remaining chain. If each bracelet is the same length, what will be the length of each bracelet in centimeters?
9514 1404 393
Answer:
16.05 cm
Step-by-step explanation:
Each bracelet will be 1/5 of 1/2 of the chain, so is
(1/5)(1/2) = 1/10
of the original length of the chain.
1/10 × 160.5 cm = 16.05 cm . . . length of each bracelet

Answer: D) The relation R is a function because for each input there is exactly one output
There's not much else to say other than what choice D already does. Visually we can use the vertical line test to confirm if we have a function or not. If we can pass a single vertical line through more than one point on a curve, then the curve isn't a function. The graph is said to have failed the vertical line test. Otherwise, the relation passes the vertical line test and we have a function.

2(6)-8=10-5
how would 2(6)-8 equal 10-5?!
Answer:
It would not
Step-by-step explanation:
10-5 is basically 2-1 so if 2x6-8 (or 2(6)-8) equals 2-1 then it would. So you start with multiplying 6 and 2 and get 12. 12-8 equals to 4-3. I didn't find your answer but I did what I could.
